SPECIFICATION forming part of Letters Patent No. 472,139, dated Apr-i15, 1892. Application filed November 2, 1891. Serial No 410,665. (Nomodel.)

To afZZ whom it may concern:

Be it known that I, WILLIAM HENRY NEW- TON, a citizen of the UnitedStates, residing at Decatur, in the county of Macon and State ofIllinois, have invented a new and useful Dehorner, of which thefollowing is a specification.

This invention relates to improvements in dehorning implements; and theobjects in view are to provide an implement for the above purpose, thesame being adapted to readily and cleanly cut 0E the horns f animalswith but slight exertion upon the part of the operator. 1

Other objects and advantages of the invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the claims.

Referring to the drawings, Figure 1 is a perspective of a dehorningimplement constructed in accordance with my invention. Fig. 2 is alongitudinal section. Fig. 3 is an elevation with one of the face-platesremoved. Fig. 4 is a detail of the stationary knife.

Like numerals of reference indicate like parts in all the figures of thedrawings.

1 1 designate a pair of similarly-constructedface-plateshavingasubstantially oblongshape and terminating at theirlower or inner ends in outwardly-disposed bearing-ears 2, between whichstrengthening-arches are formed. Each of the face-plates is providednear its upper or outer end with a circular opening 3, and one of saidplates has a removable section in which said opening is formed, and hasthe outer edge of its opening beveled to form a curved cutti 11g-edge 4.The plates are spaced apart by opposite side bars or strips 5, having atintervals perforated ears 6, which agree with corresponding ears formedat the edges of the plates, and through said ears bolts 7 are passed,whereby the two plates and the intermediate side strips 5 are securelybound together. Located in the plates for movement is a blade 8,provided at its outer end with a diagonal beveled cutting-edge 9,adapted to operate in connection with the cutting-edge 4 of the opening3 and to form a shear cut upon a horn introduced through the openings 3.The plate is provided at its inner end with a double rack-bar 10, havinga central longitudinal slot 11, which receives a transverse pin 12,passing through the two plates at their inner ends, and serving as aguide for the bar and knife.

13 designates a bell-crank lever, and 14 a companion lever of asimilarpattern. These levers are pivoted or fulcrumed by bearingbolts 15between the pairs of ears 2 of the plates, and at their outer or forwarden ds terminate in toothed sectors 16, which engage the opposite teethof the rack-bar 10, and communicate reci procatory movement to therackbar and knife. The levers 13 and 14 are provided at theirextremities with internal sockets 17, and into the same are insertedwooden handles 13. In bearing-ears 19, formed at the inner edge of thelever 13, near the fulcrum of the same, there is pivoted, as at 20, anintermediate lever 21, terminating opposite the handles 18 in a socket22. Eyes 23, formed on the lever 14 near the free end of the same, arepivotally connected by a bolt 24 to a short link 25, the inner end ofwhich is by a bolt 27 pivoted to ears 28, located upon the intermediatelever 21 at or near its center.

This completes the construction, and the operation is as follows: Tosever a horn, the levers 13 and 14 are spread, and, moving upon theirfulcrums 15 through the medium of their toothed sectors and the engageddouble rack-bar, draw the knife rearwardly 01 from over the openings 3.The openings 3 are now introduced over the horn and snug upon the same,so as to closely embrace it at the point immediately below where the cutis to be made. It now simply remains to draw the two levers 13 and 14together, the horn being severed by the united cutting of thecuttingopening 3 and the cutting-edge 9ct the blade 8 as the two arebrought together. In this manner a shear cut, clean and free fromsplintering, is made, which clean cut is further promoted by the snugembracing of the horn by the hole 3 of the lower plate. If the horn isparticularly tough and requires more than the power that may beconveniently applied through the medium of the two levers 13 and 14,thehandle 18 is removed from the lever 14 and applied to the end of theintermediate lever 2l. This lever and the lever 13 are now drawntogether, and it will be seen that the inward movement of this leverwill cause a greatly-increased force to be applied to the blade.

From the foregoing description, in connection with the accompanyingdrawings, it will be seen that l have provided a cheap and simpleconstructed dehorning device adapted to smoothly remove the hornswithout danger of cracking or fracturin g the same and that said deviceis designed to accomplish the operation with dispatch and with butlittle exertion upon the part of the operator.

Having described my invention, what I claim is l. In a dehorner,thecombinatiomwith the casing, the opposite walls of which are providedwith openings, one of the same being beveled to form a curvedcutting-edge, of opposite segmental levers fulcrumed at the innercorners of the casing and having their segmental portions provided withteeth, a blade mounted for sliding in the casing and terminating at itsouter end in a cutting-edge, a rack-bar secured at its front end to therear end of the blade and having opposite toothed edges and anintermediate longitudinal slot, said rack-bar having its teeth engagedby those of the levers, and a guide-pin passing through the walls of thecasing and the slot of the rack-bar and serving as a guide for the same,substantially as specified.

2. In a dehorner, the combination, with the casing having thecutting-opening, the sliding knife, and the rack-bar, of the oppositelevers fulcrumed at the inner corners of the casing, said leversterminating at their forward ends in toothed sectors engaging therack-bar and in rear of the same in handles, an intermediate leverfulcrumed at its forward end near the inner end of one of the levers,and a link pivotally connected to the opposite lever, to which theintermediate lever is pivoted and to said intermediate lever be tweenthe ends thereof, substantially as specified.

3. In a dehorner, the combination, with the casing having the beveledopening and the opposite pairs of bearinglugs, the sliding knife mountedfor movement in the casing, the longitudinally-slottedoppositely-toothed bar connected to the rear end of the knife, and theguide-pin located in the casing and passing through the slot of the bar,of the angular levers 13 and 14, pivoted in the bearing-ears of thecasing and terminating at their outer ends in sockets, handles removablymounted in the sockets, the intermediate lever 2l, pivoted at itsforward end to the lever 13 and at its rear end terminating in a socketadapted to receive the removable handle 1S of the lever 14, and the link25, pivotally connected to an intermediate portion of the lever 2l andto the rear of the lever 14, substantially as specified. Y

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

WILLI AM HENRY NEWTON.
